A/C high side service port

[Beast220]

I have a 98 k1500 4.3L.

A/C works great except the refrigerant doesn’t want to stay in its home.

It’s leaking out the high side service port. I could swear those are replaceable but this appears to be integral to the line. Am I just not seeing it correctly and it does come off or am I buying the whole high side line on the compressor?

Thanks

It un-threads. Dorman makes a replacement 800-955 with an actual shrader core rather than the garbage nylon ball.
